Title: Anti-theft system for motor-driven means of locomotion
Inventor: ADOMAT ROLF DIPL ING
IPC: B60R25/10
Filed: 1993-05-25
Abstract: In the case of a simple and nevertheless efficient anti-theft system for motor-driven means of locomotion, in addition to the starter contact there is integrated in the starter switch an auxiliary contact which can be closed when the ignition key is turned and is inaccessible from the outside. The auxiliary contact is connected to a release unit which is integrated in the starter switch and is connected by way of a connecting line directly, or via a switch, to at least one control unit of the means of locomotion.
Patent DE-4319896-A1 (DE)
Title: Rotary engine, prime mover and machine performing mechanical work and having pressure equalisation
IPC: F01C3/02
Filed: 1993-06-16
Abstract: A rotary engine, prime mover and machine performing mechanical work, in which blades (vanes) fastened on rotors move in annular chambers which correspond to the shape of the blades and are subdivided at a point of the circumference by a blocking disc which rotates synchronously with the driveshafts of the rotors and has a passage as a blade gate for the blades. The volumes of the working fluid (operating fluid) located in the annular chamber between the front (leading) and rear (trailing) faces of the blades and the blocking disc vary continuously, ie are compressed or expanded, as a result of which gases are compressed or expanded via inlet and outlet valves and openings, with the result that via inlet and outlet valves or openings gases are compressed or compressed gases/vapours/working fluids are expanded and in so doing perform work in the blades. The pressure equalisation is produced at the blocking disc, and energy losses due to friction are thereby reduced, due to symmetric back-to-back connection of the individual annular chamber/blade systems and to oppositely directed senses of rotation of the blades.

Title: Method for operating a burner with gaseous or liquid fuels and burner for carrying out the method
Inventor: ALTEMARK DETLEF DR ING
IPC: F23D14/02
Filed: 1993-09-07
Abstract: In a method for operating a burner with gaseous and liquid fuels at low combustion temperatures and with the formation of waste gases low in pollutants, a hyperstoichiometric mixture of fuel and combustion air is homogenised in a mixing chamber (4) upstream of the combustion chamber (7) and then led into the combustion chamber (7) via a gas-distributing device (6). In order to achieve a high stability of the burner flame and thus good controllability of the quantity of air, the mixing chamber (4) is supplied with a mixture, not ignitable on its own, of a partial stream of the fuel participating as a whole in the combustion process and of the entire quantity of the combustioin air. On entering the combustion chamber (7), the mixture thus formed is subjected to turbulence which is intense at least in certain regions. This is preferably effected via a swirl generator (15). The remaining fuel still required for a complete combustion is then injected into the mixture thus swirled. A gas lance (11) having outlet nozzles oriented orthogonally at its end is preferably used for this purpose. A burner suitable for carrying out the method is also proposed. <IMAGE>

Patent DE-4331874-A1 (DE)
Title: Circuit arrangement for limiting the ignition voltage
Inventor: KULESCH MANFRED
IPC: F02P3/045
Filed: 1993-09-21
Abstract: An ignition system for internal combustion engines with constant ignition voltage distribution is described, in which ignition system the limiting voltage of the primary current of the ignition coil can be prescribed on the basis of engine-specific requirements. Switching over takes place as a result of the state of the actuation lines which cannot occur during normal operation. By virtue of reducing the limiting voltage misfirings are avoided. In a development of the circuit arrangement according to the invention there is provision for the limiting voltage to be controlled in terms of controlling the ignition voltage requirement.

Title: Drawframe for spinning machines
Inventor: EBERHARDT ROLAND
IPC: D01H5/56
Filed: 1993-10-22
Abstract: In the top-roller carrier of a drawframe for spinning machines, the said top-roller carrier being provided with mechanical compression springs, an at least largely constant-pressure loading of the top rollers over the entire possible operating range of adjustment of the links (15) is ensured by a choice of the position of the action point (19) of the compression spring (12) accommodated in the individual slides (10) in relation to the pivot-bearing point (16) of the link (15) in the slide (10) and to the axis (17) of the top roller in the link (15). This can be assisted by additionally varying the position of the action point (19) of the compression spring (12) in dependence on the pivoting position of the link, additionally also to achieve a part relief of the top roller in a part-load position of the top-roller carrier. <IMAGE>

Title: Removing particles from liquids
Inventor: WETZEL RAINER DR ING
IPC: B03C5/00
Filed: 1993-12-28
Abstract: The procedure for cleaning a liquid containing particles uses exposure to an alternating electric field. The particles in the fluid are agitated by the field and the viscosity of the liquid is decreased to less than a quarter of its room temperature value by having the liquid heated. The electric field may or may not be homogeneous. The waveform may be sinusoidal or square wave.  The frequency and magnitude of the field are chosen so that the particles can move rapidly transverse to the flow direction of the mixture. Alternatively, the field may be an electrostatic one first of one polarity and then of the opposite one.

Patent DE-4412768-A1 (DE)
Title: Method for the production of particles from metallic melt
Inventor: ANDERSON IVER E
IPC: B22F9/08
Filed: 1994-04-13
Abstract: A metallic melt is finely divided by means of an atomisation gas under high pressure, the temperature of the melt and the composition of the atomisation gas for this process being chosen such that the gas and the melt react in the resulting atomised powder particles in the atomisation spray zone to form a heat-resistant or intermetallic compound. Another proposal is to atomise metallic melt with the aid of a gas mixture as the atomisation gas under high pressure, with the temperature of the melt and the ratio of a reactive gas to a carrier gas being chosen so that the powder particles formed exhibit a supersaturated solid solution of the atomic species of the reactive gas in the particles. The powder particles are then subjected to a heat treatment in order to separate out dispersants in situ to give a material reinforced by means of dispersion.

Title: Removing dust and non-polar fluid droplets from effluent gases
Inventor: TRIELOFF SALKA
IPC: B01D50/00
Filed: 1994-04-27
Abstract: The effluent gas enters the absorption fluid, e.g. a non-polar oil, in the absorption chamber. The particles of solid  and the liq. droplets are wetted by and coalesce with the fluid at the surface. A hydrostatic pressure is exerted, forming froth and bubbles in the absorption fluid and the resulting mixt. rushes like a torrent, into the impact or contact chamber. The wetting of the particulates continues and the mixt. is pushed on into a second contact chamber. The gas, now cleaned, is drawn off and sediment falls to the base of the absorption chamber, to be removed.Also claimed is the appts. for carrying out the above process.

Title: Operating system for operating high pressure gas discharge lamp
Inventor: ERIGUCHI HIROYASU
IPC: H05B41/292
Filed: 1994-07-20
Abstract: The switching frequency of the current converter circuit (11) is adjusted in the unloaded condition of the HP gas discharge lamp (DL), by the control unit (12), to a frequency (f0), which is greater than the resonant frequency (fR) of the series resonant circuit (13) and lies near to it. The lamp (DL) is ignited with a high voltage, which is produced at the capacitor (C) in the series resonant circuit (13). The switching frequency of the converter circuit (11) in the active condition of the lamp (DL) is adjusted to a frequency (f1). This frequency is lower than the resonant frequency (fR) of the series resonant circuit, which however causes no unstable arc discharge, due to the occurrence of any acoustic resonances. Whilst the activated condition of the lamp is maintained with a voltage, which is produced at the capacitor (C) at the series circuit (13).
